verify_table_headers(9)

✨ NAME ✨

okay so bestie, this is the verify_table_headers(9) page from the Kernel API Manual, and it is literally here to verify_table_headers — verify that the tables headers are as expected 💅✨

---

🎀 SYNOPSIS 🎀

int verify_table_headers (struct table_header **tables , int flags );

---

🧚 ARGUMENTS 🧚

• tables — array of dfa tables to check, and it is NOT NULL (so do not come in here with a null vibe 🙈)
• flags — flags controlling what type of accept table are acceptable ✨

---

💅 DESCRIPTION 💅

It assumes the dfa has already gone through the first pass verification done by unpacking 🫶 Like, that part is already handled, bestie — this function is not doing the whole unpacking situation itself.

---

🫶 NOTE 🫶

this does not validate accept table values 🫣 keep that in mind, okay?

---

⭐ RETURN ⭐

Returns 0; otherwise you get an error code on failure to verify. periodt 💀
